APPARATUS FO R MAKING CARBONATED BEVERAG ES.

SPECIFICATION' forming part of Letters Patent No. 467,916, dated February 2, 1892.

Application filed March 7, 1891. Serial No. 384,183. (No model.)

To all whom t may concern.-

Beit known that I, IIENRY OARSE, a citizen of the United States, residing at the city ol Rock Island, in the county of Rock Island and State of Illinois, have invented a new and useful Soda-Tater Apparatus, of which the following isa specification.

My invention relates to what isknown as the continuous system of making carbonated beverages, Where the mixture is stored in a closed reservoir under pressure to be drawn off in bottles or other vessels; but the particular part in the process to which my invention relates is uniting the fluid and gas, applying pressure thereto, and mixing the same; and the objects of my invention are, first, to use one pump-cylinder for pumping the fluid and gas at alternate strokes of the piston, the iluid reducing the heat of the cylinder, which would otherwise be produced by the gas alone entering such cylinder; second, to discharge the fluid and gas While under a state of pressure, in one common receivingchamber, connected with another chamber by a series of line perforations through which the fluid and gas is forced and mixed; third, to continue the passage of the fluid and gas thus mixed through a pipe having at intervals within such pipe perforated thimbles or disks, the passage through such perforations causing further agitation and mixing of the liuid and gas, and, fourth, to arrange valves forced against the valve-seat by spring-pressure, with means for increasing and decreasing the degree of pressure of the spring against the valve, whereby the passage of the fluid, whether mixed or unmixed with the gas, may be regulated. I accomplish these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure l is a view of my apparatus in elevation, the inlet fluid-pipe, its chuck-valve, and theair-chamber being removed from the pump-cylinder. Fig. 2 is a vertical sectional view of the chambers for receiving the fluid and gas and the perforated passage-way between the same, such view being enlarged. Fig. 3 is a vertical sectional view of a regulating-valve enlarged. Fig. 4 is a plan view, inverted and enlarged, of the disk used in the regulating-valve. Fig. 5 is a plan View, enlarged, of the perforated connection between the chambers illustrated in Fig. 2. Fig. 6 is a vertical sectional view of the pipe and perforated thimble. Fig. is a view of the front end of the pu mp-cylinder, the head and piston being removed, and also showing a portion of the inlet and outlet water or iuid pipe, the chuck-valve in such outlet-pipe and the relief-valve and pipe attached thereto; and Fig. 8 is a View taken on the line ir of Fig. 7, showing the chuck-valve in the outletiiuid pipe and the connection of the reliefpipe and relief-valve therewith.

Similar letters and figures refer to similar parts throughout the several views.

l0 is a pump-cylinder; ll, its piston-rod provided with a suitable piston within the cylinder, which is not shown, and it will be understood that the piston-rod is connected with a suitable cross-head and with connecting-rods and drivingcrank from a motor, which are not shown in the drawings. The pump-cylinder l0 is secured in anysuitable manneras, for instance, by the frame l-to the bedplate or floor A, and is provided with a fluidinlet pipe, which is fitted and secured watertight in the perforation 13 of the cylinder, which perforation may be in the end or in the side near an end of such cylinder. Such inletpipe is not shown in the drawings, except at 13a in Fig. 7, as its construction is well understood and common to all pumps. So, too, the inlet-pipe is provided with a chuck-valve or other suitable Valve and airchamber, neither of which are shown in the drawings, as their use in general in pumps and their construction and operation are well under stood. A perforation similar to 13 is made in the opposite side of the cylinder, into which is fitted the fluid-outlet pipe 14. water-tight, such pipe also being provided with a chuckvalve or other suitable valve. This portion of the said pipe and its valve are not shown in the drawings, except at 14b of Figs. 7 and 8, for the same reasons which I have stated relating to the duid-inlet pipe. Connected to said outlet-pipe and its chuck-valve is a relief-pipe l5, which is provided with the regulating-valve IG.

I will now describe the construction of the regulating-valve 16, which is provided with a well 17, horizontal inlet passage-way 1S, and horizont-al outlet passage-way l 9, the latter being above or out of line with the former, the outer ends of the passage-ways terminating in the cylindrical formed threaded apertures 20 for the reception of the threaded ends of ICO vthe relief-pipa A vertical cylindricallyformed aperture 21 communicates with the well and horizontal passage-ways. A disk 22 has attached upon itsunder side three vertical legs 23 at points equidistant from each other, and attached to the upper side ot' said disk centrally is a vertical pivot 24. Thelegs of the disk enter the well and, rest upon the bottom thereof, while a lower portion of the bottom of the disk rests upon the door of the horizontal passage-way 19, and theremaining view of such disk adjoins the wall of the aperture 21. The coil-spring 25 is placed within the vertical aperture 21, the bottom of the coil resting upon the disk and surrounding its pivot 24, the interior of such coil-spring being provided midway with a short brass or metal core 26, of size and form to be tightly grasped and held by its surrounding; coils. The upper portion of thevertical aperture 211 is threaded, as at 27, which aperture receivesthe threaded follower-stem 2S, and to-prevent leakage of gas such stem is surrounded by a stufting-box 29,attached to the wall oi' the vertical aperture 21', and the follower-stein is provided with a handle 30 for screwing or unscrewingsuch stem. At the end of-v the cylinder opposite to the end where the fluid is admitted and ejected are twopipes 31 and. 32, entering such cylinder and fitted therein gastifg-ht. rlhe pipe 31' is the gas-inlet pipe, which'Y admits the carbonio-acid gas from a flask or receiver (not shown in the draW-ings)to the cylinder, and the other pipe 32 conveys the carbonic-acidf gas from the cylinder tothe common receiving-chamber, and the pipe 14 also. conveys-the iluid to the same` common receiving-chamber. The inlet gas-pipe 31 and the outlet-pipe 32 are each` provided with chuckstruction. and use of such valves being well understood without further description or explanation. The receiving-chamber is connected with another by a series of'iine perforations, the object being to-mingle the fluid and gas together in the common chamber, and by means ofthe pressure exertedA from thepum-p to force suchmass troni the com mon chamber` through the perforations into the adjacent chamber for thepu-rpose of' mixing the gas with thefluid, and to designate this part of my device as an` entirety I will denominateV it a mixing-Vessel 34.

VariousI forms of constructing my mixingvessel may be made; but I prefer, however, toenibody it inV the form which I will now describe: I connect the eXtreme-ends of the duidoutlet pipe 14 and the gas-outlet pipe 32 at'vright angles to each other, as at 35, by a suitable joint. I use a base 36, having a horizontal aperture 37 through it, the ends of which are interiorly threaded, as at 38 and 39, andit is alsov provided with a cross vertical registering perforation, as at 40. At the intersection ot the horizontal perforation 37 and vertical perforation 40 the chamber is enlarged, and the lower and upper portions of the vertical f fer.

.within suchl pipe, as shown in Fig. (5.

nection with the base, so as to form tight joints c or connections with such base. The outlet f gas-pipe 32 is continued vertically above v theI point of intersection with the huid-outlet pipe 14, forming the common receiving-chamber 43, the top of which chamber is covered with a cap 44, ii-nel-y perforated. I place on the upperpart'of the base an 'inverted cup 45, threaded to en gage with the threads 420i the upper portion of the vertical perforation of the base,v so as to makea tight joint or connection therewith, the. interior of which cup forms the additional chamber 46, connected with the common receiving-chamber 43- by the perforations through the cap 44, separating` the-chambers. The end of theoutlet-pipe 47 from the mixing-vessel is exteriorly'threaded to make a tight joint or connection with the threaded portion of the horizontal aperture 37 through the base 36.

For the purpose of further agitating` and mixing the liuid and gas I conduct the mass through a series of vertical pipes parallel to Leach other and connected, forcing the same at intervals through fine perforaticns in obstruc-tions placed in such pipes. embody this-portionY of my invention in this form; but it will be understood that many modifications and changes-may be made withlout departing from thescope of my invention.

be secured to the licor or bed-plate A by a frame B C or in any other suitable manner.

In operation-as, for instance, in the manufacture of soda-water-the water is pumped in the cylinder by an inlet-pipe communicating with such cylinder through the orifice 13, and carbonio-acid gas is also pumped into the cylinder by means of the inlet gaspipe 31, while such Water is ejected from the cylinder through the pipe 14 and the gas through pipe 32. The forward stroke of the piston pumps water into the cylinder and at the same time ejects the gas from such cylinder, and the return or backward stroke of the piston pumps gas into the cylinder and ejects the water therefrom. It itis found that too much water is being pumped into the mixing-vessel, tlie same may be regulated through the regulating-valve 16 by unscrewing the stem 28, so as to relieve the disk 22 from great pressure from the coil-spring, or the pressure may be increased when desired by screwing down such stem. The gas and water, when so pumped, are discharged into the chamber 43 of the mixing-vessel, and the pressure from the pump causes such gas and water to pass through the perforations in the cap 44 into the chamber 46, thus mingling the gas and water together, and the continuation of the pressure forces the same through the aperture 37 in the base and through the outletpipe 47 and down pipes 48 and up pipes 49 and through the exit-pipe 5G to the flask or receiver.

In the passage of the gas and` Water from the mixing-vessel by reason of the continued pressure the same is caused to pass through the perforated thimble in each vertical pipe 49, thus causing' further mixing of the gas and water.

The valve 57 may be regulated in the same manner as already described as to valve 16, througli which means the discharge of the water and gas through the eXit-pipe may be controlled.

It will be understood that many modifica-pu tions and changes may be made in my device without departing from the scope of my invention, and from the description given persons skilled in the art will understand the construction and use of my device.

I am aware that it is old in a carbonating apparatus to combine with a receiver and a pump for supplying liquid and gas thereinto a series of incorporatorvessels, with a pipe in each incorporator-vessel leading upward therein, the pipes being of gradually-decreasing size from the inlet to the outlet end of the series, so that the liquid and gas delivered by the pump are discharged through the pipe in the first incorporator-vessel and fall from the top to the bottom of such vessel, such liquid and gas being thence delivered to a second incorporatorvessel in the same manner, and so on through all the seriesuntil it is finally delivered into a receiver.

I am also aware that it is old in an apparatus for charging liquors with gases to combine with a tank and a tube delivering gases therein an inverted cup or receiver so located and fixed upon a shaft revolving within said tank and operated by power from without as to revolve with said shaft and receive the gases delivered by said tube, such inverted cup or receiver having rigidly fixed radiallyprojecting perforated tubes with open external ends, and also to provide two or more similarly-arranged tanks connected by systems of pipes, whereby the gases and liquors may pass from an upper tank to a lower tank through a connecting liquor-discharging pipe prolonged Within said lower tank near its top in any convenient direction, the part within said lower tank being formed with perforations. I do not claim such combinations, broadly.

`What I claim as new, and desire to secure by Letters Patent, is-

In a soda-water apparatus, the combination, with a pump and pipes for discharging liquid and gas therefrom, of the mixing-vessel provided with the chambers 43 and 46 and the finely-perforated cap between such chambers and connecting the same, said liquid and gas discharging pipes from said pumps entering into the chamber 43, and the outlet-pipe leading from said chamber 46, substantially as described.

2. In a soda-water apparatus, the combination, with a pump and passageway through which liquid and gas are discharged while mixed, of' a series of vertical pipes connected by semicircular pipes in alternate pairs at top and bottom, each upper semicircular connecting-pipe being interiorly provided with a rigidly-fixed perforated thimble for the passage of the liquid and gas, the first of such vertical pipes of the series connected with said passage-way through which such liquid and gas are discharged while mixed, and the last of such vertical pipes of the series connected with the exit-pipe, substantially as described.

3. In a soda-water apparatus, the combination, with the pump, of the liquid-outlet pipe 14, the relief-pipe 15, the regulating-valve 1G,

the gas-outlet pipe 32, said outlet-pipes leadt ing from the pump to the chamber 43 of the mixing-vessel, the mixing-vessel composed of the chambers 43 and 4G and connected by the perforated cap 44, the outlet-pipe 47, leading from the chamber 4G to the series of vertical pipes, the series of vertical pipes 4S and 49, connected in alternate pairs by the semicircular pipes 50 and 51 at top and bottom,the perforated thimble located within each semicircular pipe 5l, and the exit-pipe 56, leading from the last vertical pipe of the series, and such exit-pipe provided with the regulating-valve 57, for the purposes stated, and substantially as described.
